Eli5 , How do windsurfers get back to where they started if the wind is only blowing one way?

Question

The only way I can think that this would be possible is if the wind was blowing directly onshore?

Edit: thanks for all the well thought out replies. I think I’ve got it figured out know, I’ve always Been a bit confused about ships tacking into to wind and I think the key thing I was missing was the sail being using like as an airfoil creating pull, used in tandem with with the fins/keel .

Sailing downwind is rarely done by windsurfers as you would have to stretch the sail out to catch the wind and pretty much only go as fast as the wind is blowing…
